Water → Ethyl 5-hydroxy-2-(5-methyltetrazol-1-yl)benzoate

Participants

Reaction Steps

Ethyl 5-acetoxy-2-(5-methyltetrazol-1-yl)benzoate (164 g, 0.565 mol) was dissolved in 500 mL of DMF and immersed in a water bath. Potassium ethoxide (52.3 g, 0.621 mol) was added to this solution portionwise, keeping the reaction temperature below 40° C. After 30 minutes, the reaction was poured into 4 L of water and ammonium chloride was added to the solution until the product precipitated. After one hour of stirring, the precipitate was filtered and dried under a flow of air to give 98.5 g of ethyl 5-hydroxy-2-(5-methyltetrazol-1-yl)benzoate as a white solid.
